[0043] Embodiment 1:

[0044] Reference Figures 1 to 4 , Figure 1It is a schematic diagram of the overall structure of the utility model; Figure 2 It is a schematic diagram of the exploded structure of the utility model; Figure 3 It is a schematic diagram of the structure of the adjusting member in the embodiment of the utility model in the disassembled state; Figure 4 It is a schematic diagram of the structure of the extrusion part in the embodiment of the utility model in the exploded state.

[0045] This embodiment provides a drainage tube with adjustable flow rate, including a drainage tube 1 and an adjusting member 2, specifically:

[0046] The adjusting member 2 includes a sleeve 21, which is horizontally sleeved on the outside of the drainage tube 1; the sleeve 21 is a cylindrical hollow structure that matches the drainage tube 1, and is convenient for horizontally sleeved on the outside of the drainage tube 1;

[0047] An adjustment frame 22 is vertically fixed to the top of the outer circumferential surface of the sleeve 21. The adjustment frame 22 includes a vertical rod and a horizontal plate. The vertical rod extends in the vertical direction, and the horizontal rod extends in the horizontal direction. There is a distance between the horizontal rod and the sleeve 21. The vertical rod can support the horizontal rod. Of course, the distance between the vertical rod and the horizontal rod also provides an operating space for the adjustment member.

[0048] A pressing groove 211 is vertically formed through the top of the outer circumferential surface of the sleeve 21. The pressing groove 211 is formed by the top of the sleeve being recessed toward the bottom side of the sleeve 21. The setting of the pressing groove 211 facilitates the position of the extrusion block 241 to be seen.

[0049] An adjusting cylinder 23 is fixedly passed through vertically downward in the middle of the adjusting frame 22, and a plurality of baffles 231 are horizontally arranged on one side of the inner circumference of the adjusting cylinder 23 in the vertical direction, and the plurality of baffles 231 are spaced apart in the vertical direction and are arranged in parallel, and the baffles 231 are of a C-shaped structure, the inner ring opening of the C-shaped structure faces the central axis of the adjusting cylinder 23, and the baffles 231 are fixed on the inner circumference of the adjusting cylinder 23, specifically, the outer ring of the baffles 231 is fixed on the inner circumference of the adjusting cylinder 23; optionally, there is a spacing between adjacent baffles in the vertical direction, and the flow rate can be controlled by adjusting the spacing between the baffles 231 and the number of the baffles 231; optionally, a scale is marked on the adjusting cylinder 23, and the flow rate is determined according to the degree of the scale;

[0050] An extrusion piece 24 is provided below the adjusting cylinder 23. The extrusion piece 24 includes an extrusion block 241. The extrusion block 241 is horizontally provided below the adjusting cylinder 23. The extrusion block 241 is inserted into the pressing groove 211 of the sleeve 21 to extrude the drainage tube 1. The top surface of the extrusion block 241 may be a plane, and the bottom surface of the extrusion block 241 may be an arc-shaped surface. The extrusion block 241 is in extrusion contact with the drainage tube 1. When the extrusion block 241 moves downward, the greater the distance, the greater the degree of extrusion of the drainage tube 1, and the smaller the flow rate through the drainage tube 1.

[0051] Two guide rods 245 are symmetrically and vertically fixed on the top surface of the extrusion block 241. In the horizontal direction, there is a gap between the two guide rods 245, and the two guide rods 245 vertically penetrate the adjustment frame 22 upward. The function of the guide rods 245 is to stabilize the extrusion block 241, ensure that the extrusion block 241 moves in the vertical direction, and prevent the extrusion block 241 from tilting in the horizontal direction.

[0052] A connecting rod 242 is vertically rotatably connected to the top surface of the extrusion block 241, and the connecting rod 242 is vertically inserted into the interior of the adjusting cylinder 23, the connecting rod 242 is located between the two guide rods 245, and a card 244 is horizontally fixed to the top of the connecting rod 242, and the card 244 is a C-shaped structure, and the baffle 231 can play a role in blocking the card 244. Of course, the shape of the baffle 231 needs to cooperate with the card 244, so that the baffle 231 can block the card 244; the card 244 is inserted between the two baffles 231, and the baffle 231 can block the card 244.

[0053] An insertion rod 243 is vertically fixed on the top surface of the card 244, and the insertion rod 243 vertically penetrates the top end of the adjusting cylinder 23. During use, the rotating insertion rod 243 drives the card 244 on the connecting rod 242 to rotate. When the rotating insertion rod 243 drives the card 244 on the connecting rod 242 to rotate in the direction away from the blocking piece 231, the connecting rod 242 on the extrusion block 241 lacks the blocking piece 231 in the adjusting cylinder 23, and the extrusion piece 24 slides vertically on the adjusting frame 22. The extrusion block 241 is inserted into the pressing groove 211 of the sleeve 21. When the rotating insertion rod 243 drives the card 244 on the connecting rod 242 to rotate in the direction close to the blocking piece 231, the blocking piece 231 of the adjusting cylinder 23 blocks the card 244 on the connecting rod 242, so that the height of the extrusion block 241 can be determined.

[0054] The working principle of the drainage tube with adjustable flow in the utility model is:

[0055] When in use, the adjusting member 2 is sleeved on the outer wall of the drainage tube 1, so that the adjusting member 2 and the drainage tube 1 are plugged and assembled together;

[0056] When adjusting the flow of the drainage tube 1, first rotate the rod 243 on the adjusting cylinder 23 on the adjusting frame 22 according to the flow demand of adjusting the drainage tube 1. The rotating rod 243 drives the card 244 on the connecting rod 242 to rotate away from the baffle 231. The connecting rod 242 on the extrusion block 241 lacks the baffle 231 of the adjusting cylinder 23 to block it. Then, the extrusion piece 24 slides down vertically on the adjusting frame 22, and the extrusion block 241 is inserted into the pressing groove 211 of the sleeve 21. Then, the rotating rod 243 drives the card 244 on the connecting rod 242 to rotate close to the baffle 231. The baffle 231 of the adjusting cylinder 23 blocks the card 244 on the connecting rod 242 to maintain the flow of the drainage tube 1.

[0057] When not in use later, the adjusting member 2 can be taken out from the drainage tube 1 and separated from the drainage tube 1 . The adjusting member 2 can be reused, thus ensuring that resources are not wasted.

[0058] Compared with the related art, the present invention achieves at least the following beneficial effects:

[0059] 1. The flow rate can be adjusted. Specifically, the adjusting member 2 is plugged and assembled with the drainage tube 1 when in use. When adjusting the flow rate of the drainage tube 1, firstly, according to the flow rate demand of the drainage tube 1, the plug rod 243 on the adjusting tube 23 on the adjusting frame 22 is rotated, and the rotating plug rod 243 drives the card 244 on the connecting rod 242 to rotate away from the blocking piece 231. The connecting rod 242 on the extrusion block 241 lacks the blocking piece 231 of the adjusting tube 23, and then the extrusion member 24 slides down vertically on the adjusting frame 22, and the extrusion block 241 is inserted into the pressing groove 211 of the sleeve 21. Then, the rotating plug rod 243 drives the card 244 on the connecting rod 242 to rotate close to the blocking piece 231, and the blocking piece 231 of the adjusting tube 23 blocks the card 244 on the connecting rod 242, so as to maintain the flow rate of the drainage tube 1;

[0060] 2. The adjusting member is reusable. Specifically, the adjusting member 2 and the drainage tube 1 are not an integral structure and can be disassembled. When not in use, the adjusting member 2 and the drainage tube 1 can be separated and reused, thereby ensuring that resources are not wasted.

[0061] Embodiment 2:

[0062] This embodiment provides a drainage tube with adjustable flow rate, including a drainage tube 1 and an adjusting member 2, specifically:

[0063] The adjusting member 2 includes a sleeve 21, which is horizontally sleeved on the outside of the drainage tube 1; the sleeve 21 matches the drainage tube 1 and is a cylindrical hollow structure;

[0064] An adjustment frame 22 is vertically fixed to the top of the outer circumferential surface of the sleeve 21. The adjustment frame 22 includes a vertical rod and a horizontal plate. The vertical rod extends in the vertical direction, and the horizontal rod extends in the horizontal direction. There is a gap between the horizontal rod and the sleeve 21.

[0065] A pressing groove 211 is vertically formed through the top of the outer circumferential surface of the sleeve 21. The pressing groove 211 is formed by the top of the sleeve being concave toward the bottom side of the sleeve 21.

[0066] An adjusting cylinder 23 is fixedly passed vertically downward through the middle of the adjusting frame 22, and a plurality of baffles 231 are horizontally arranged along the vertical direction on one side of the inner circumference of the adjusting cylinder 23, and the plurality of baffles 231 are spaced apart along the vertical direction and are arranged in parallel, and the baffles 231 are of a C-shaped structure, the inner ring opening of the C-shaped structure faces the central axis of the adjusting cylinder 23, and the baffles 231 are fixed on the inner circumference of the adjusting cylinder 23;

[0067] An extrusion member 24 is provided below the adjusting tube 23. The extrusion member 24 includes an extrusion block 241. The extrusion block 241 is horizontally provided below the adjusting tube 23, and the extrusion block 241 is inserted into the pressing groove 211 of the sleeve 21 to extrude the drainage tube 1. The extrusion block 241 is in extrusion contact with the drainage tube 1. When the extrusion block 241 moves downward, the greater the degree of extrusion of the drainage tube 1, the smaller the flow rate through the drainage tube 1.

[0068] Optionally, the top surface of the extrusion block 241 may be a plane, and the bottom surface of the extrusion block 241 may be an arcuate surface. It is understandable that the drainage tube 1 is usually a hollow circular tube. If the bottom surface of the extrusion block 241 may be an arcuate surface, which matches the cross-section of the drainage tube 1, it is easier to extrude the drainage tube 1 and control the flow rate.

[0069] Two guide rods 245 are symmetrically and vertically fixed on the top surface of the extrusion block 241. There is a gap between the two guide rods 245 in the horizontal direction, and the two guide rods 245 are vertically upward and penetrate the adjustment frame 22.

A card 244 is horizontally fixed to the top of the connecting rod 242, and the card 244 is a C-shaped structure, and the blocking piece 231 can play a role in blocking the card 244;

[0071] An insertion rod 243 is vertically fixed on the top surface of the card 244, and the insertion rod 243 vertically penetrates the top end of the adjusting cylinder 23. During use, the rotating insertion rod 243 drives the card 244 on the connecting rod 242 to rotate. When the rotating insertion rod 243 drives the card 244 on the connecting rod 242 to rotate in the direction away from the blocking piece 231, the connecting rod 242 on the extrusion block 241 lacks the blocking piece 231 in the adjusting cylinder 23, and the extrusion piece 24 slides vertically on the adjusting frame 22. The extrusion block 241 is inserted into the pressing groove 211 of the sleeve 21. When the rotating insertion rod 243 drives the card 244 on the connecting rod 242 to rotate in the direction close to the blocking piece 231, the blocking piece 231 of the adjusting cylinder 23 blocks the card 244 on the connecting rod 242, so that the height of the extrusion block 241 can be determined.

[0072] A flow-adjustable drainage tube of this embodiment is described in detail on the sleeve. Figure 3 A rubber ring 213 is fixed on the inner wall of the sleeve 21, and a soft pad 212 is horizontally fixed at the bottom end of the inner wall of the sleeve 21. The drainage tube 1 is inserted through the sleeve 21. The soft pad 212 fixed on the inner wall of the sleeve 21 increases the friction between the outer wall of the drainage tube 1 and the inner wall of the sleeve 21, thereby improving the stability during assembly.

[0073] Embodiment 3:

[0074] This embodiment provides a drainage tube with adjustable flow rate, including a drainage tube 1 and an adjusting member 2, specifically:

The vertical rod extends in the vertical direction, and the horizontal rod extends in the horizontal direction. There is a gap between the horizontal rod and the sleeve 21.

[0077] A pressing groove 211 is vertically formed through the top of the outer circumferential surface of the sleeve 21. The pressing groove 211 is formed by the top of the sleeve being concave toward the bottom side of the sleeve 21.

[0078] An adjusting cylinder 23 is fixedly passed vertically downward through the middle of the adjusting frame 22, and a plurality of baffles 231 are horizontally arranged along the vertical direction on one side of the inner circumference of the adjusting cylinder 23, and the plurality of baffles 231 are spaced apart along the vertical direction and are arranged in parallel, and the baffles 231 are of a C-shaped structure, the inner ring opening of the C-shaped structure faces the central axis of the adjusting cylinder 23, and the baffles 231 are fixed on the inner circumference of the adjusting cylinder 23;

[0080] Optionally, the top surface of the extrusion block 241 may be a plane, and the bottom surface of the extrusion block 241 may be an arcuate surface. It is understandable that the drainage tube 1 is usually a hollow circular tube. If the bottom surface of the extrusion block 241 may be an arcuate surface, which matches the cross-section of the drainage tube 1, it is easier to extrude the drainage tube 1 and control the flow rate.

During use, the rotating insertion rod 243 drives the card 244 on the connecting rod 242 to rotate. When the rotating insertion rod 243 drives the card 244 on the connecting rod 242 to rotate in the direction away from the blocking piece 231, the connecting rod 242 on the extrusion block 241 lacks the blocking piece 231 in the adjusting cylinder 23, and the extrusion piece 24 slides vertically on the adjusting frame 22. The extrusion block 241 is inserted into the pressing groove 211 of the sleeve 21. When the rotating insertion rod 243 drives the card 244 on the connecting rod 242 to rotate in the direction close to the blocking piece 231, the blocking piece 231 of the adjusting cylinder 23 blocks the card 244 on the connecting rod 242, so that the height of the extrusion block 241 can be determined.

[0084] On this basis, the material of the regulating member of the drainage tube with adjustable flow in this embodiment is described in detail, please refer to Figures 1 to 4 In this embodiment, the material of the adjusting piece is PVC, which stands for polyvinyl chloride (Polyvinylchloride), a general-purpose plastic and the most important type of vinyl polymer. PVC has excellent corrosion resistance, insulation, flame retardancy and mechanical strength, and is easy to process. The adjusting piece made of PVC in the utility model can be repeatedly used.

[0085] In addition, since PVC is resistant to high temperatures, the adjusting member 2 can be sterilized at high temperatures before being reused, so that the adjusting member 2 can be reused.

[0086] Embodiment 4:

[0087] This embodiment provides a drainage tube with adjustable flow rate, including a drainage tube 1 and an adjusting member 2, specifically:

[0088] The adjusting member 2 includes a sleeve 21, which is horizontally sleeved on the outside of the drainage tube 1; the sleeve 21 matches the drainage tube 1 and is a cylindrical hollow structure;

[0089] An adjustment frame 22 is vertically fixed to the top of the outer circumferential surface of the sleeve 21. The adjustment frame 22 includes a vertical rod and a horizontal plate. The vertical rod extends in the vertical direction, and the horizontal rod extends in the horizontal direction. There is a gap between the horizontal rod and the sleeve 21.

[0090] A pressing groove 211 is vertically formed through the top of the outer circumferential surface of the sleeve 21. The pressing groove 211 is formed by the top of the sleeve being concave toward the bottom side of the sleeve 21.

[0091] An adjusting cylinder 23 is fixedly passed vertically downward through the middle of the adjusting frame 22, and a plurality of baffles 231 are horizontally arranged along the vertical direction on one side of the inner circumference of the adjusting cylinder 23, and the plurality of baffles 231 are spaced apart along the vertical direction and are arranged in parallel, and the baffles 231 are of a C-shaped structure, the inner ring opening of the C-shaped structure faces the central axis of the adjusting cylinder 23, and the baffles 231 are fixed on the inner circumference of the adjusting cylinder 23;

[0092] An extrusion member 24 is provided below the adjusting tube 23. The extrusion member 24 includes an extrusion block 241. The extrusion block 241 is horizontally provided below the adjusting tube 23, and the extrusion block 241 is inserted into the pressing groove 211 of the sleeve 21 to extrude the drainage tube 1. The extrusion block 241 is in extrusion contact with the drainage tube 1. When the extrusion block 241 moves downward, the greater the degree of extrusion of the drainage tube 1, the smaller the flow rate through the drainage tube 1.

[0093] Optionally, the top surface of the extrusion block 241 may be a plane, and the bottom surface of the extrusion block 241 may be an arcuate surface. It is understandable that the drainage tube 1 is usually a hollow circular tube. If the bottom surface of the extrusion block 241 may be an arcuate surface, which matches the cross-section of the drainage tube 1, it is easier to extrude the drainage tube 1 and control the flow rate.

[0094] Two guide rods 245 are symmetrically and vertically fixed on the top surface of the extrusion block 241. There is a gap between the two guide rods 245 in the horizontal direction, and the two guide rods 245 are vertically upward and penetrate the adjustment frame 22.

[0095] A connecting rod 242 is vertically rotatably connected to the top surface of the extrusion block 241, and the connecting rod 242 is vertically inserted into the inside of the adjustment cylinder 23, and the connecting rod 242 is located between the two guide rods 245. A card 244 is horizontally fixed to the top of the connecting rod 242, and the card 244 is a C-shaped structure, and the blocking piece 231 can play a role in blocking the card 244;

[0096] An insertion rod 243 is vertically fixed on the top surface of the card 244, and the insertion rod 243 vertically penetrates the top end of the adjusting cylinder 23. During use, the rotating insertion rod 243 drives the card 244 on the connecting rod 242 to rotate. When the rotating insertion rod 243 drives the card 244 on the connecting rod 242 to rotate in the direction away from the blocking piece 231, the connecting rod 242 on the extrusion block 241 lacks the blocking piece 231 in the adjusting cylinder 23, and the extrusion piece 24 slides vertically on the adjusting frame 22. The extrusion block 241 is inserted into the pressing groove 211 of the sleeve 21. When the rotating insertion rod 243 drives the card 244 on the connecting rod 242 to rotate in the direction close to the blocking piece 231, the blocking piece 231 of the adjusting cylinder 23 blocks the card 244 on the connecting rod 242, so that the height of the extrusion block 241 can be determined.

[0097] On this basis, a drainage tube with adjustable flow rate in this embodiment is described in detail for the adjustment cylinder, please refer to Figures 1 to 4 The regulating cylinder 23 is made of transparent material, and the baffle 231 is fixed on the inner circumference of the regulating cylinder 23. The baffle 231 is used to block the card 244. If the regulating cylinder 23 is made of transparent material, such as transparent PVC, it is easy to observe which baffle 231 the card 244 is engaged with, so as to determine the flow rate more intuitively. If the regulating cylinder 23 is provided with a scale along the vertical direction, the scale value can be directly read, which is more convenient to use.

[0098] It can be seen from the above embodiments that the drainage tube with adjustable flow provided by the utility model achieves at least the following beneficial effects:

[0099] The utility model can adjust the flow rate. When in use, the adjusting piece and the drainage tube are plugged and assembled together. When adjusting the flow rate of the drainage tube, firstly, according to the flow rate demand of the drainage tube, the plug rod on the adjusting cylinder on the adjusting frame is rotated, and the rotating plug rod drives the card on the connecting rod to rotate away from the blocking sheet, and the connecting rod on the extrusion block is blocked by the blocking sheet of the adjusting cylinder, and then the extrusion piece slides down vertically on the adjusting frame, and the extrusion block is inserted into the pressing groove of the sleeve, and then the rotating plug rod drives the card on the connecting rod to rotate in the direction close to the blocking sheet, and the blocking sheet of the adjusting cylinder blocks the card on the connecting rod to maintain the flow rate of the drainage tube;

[0100] 2. The regulating piece of the utility model can be reused. When not in use, the regulating piece can be separated from the drainage tube. Thus, the device for regulating the flow rate in the form of the drainage tube is not integrated. It can be disassembled after use and reused, ensuring that resources are not wasted.

[0101] 3. The utility model does not need to improve the structure of the drainage tube, and has a wider range of applications;

[0102] 4. The utility model has a simple structure and low production cost.
